Needs Work

This APP has tremendous upside, but still needs some work...
- Conversation mode works fairly well until attempting to move MSGS from Inbox to another Folder... APP crashes...
- When replying to MSG there's no MSG break between the last MSG and the reply MSG...
- Unable to perform AO functions in DTS...

Not worth the money

I had to send encrypted emails unexpectedly during a TDY with no access to a post library. I painfully paid the insane cost to ensure certain immediate actions were able to be completed. However, this app continuously crashes when trying to encrypt or randomly loses the ability to recognize your certificates. It is highly frustrating to rewrite emails multiple times or restart your device when you pay $120 dollars for an app.

The issue with Teams is still an issue. Do not waste your money. The benefit definitely does not outweigh the downfalls. Drop the price to $10 maybe worth the hassle but I could buy a refurbished laptop for the cost of the cac reader (140) and app (120).

No longer workd

With recent changes of DoD Outlook OWA access certificates am unable to access due to defaulting to email certificate. The changes now require CAC holders to use the Authentication certificate and not the Email certificates for logging into OWA. An update to this app is needed.
